Have you had any issues with stress fractures in your undercounted sink? We recently had 4 concrete countertops poured in place with undercounted sinks and one of the bathroom sinks ended up cracking after 2 months. The others seem fine so far, so I'm wondering if the sink was cracked from the beginning.???
